Risk factors attributed to failure of ultrasound-guided compression for post-cardiac catheterization femoral artery pseudoaneurysms

Background: Femoral pseudoaneurysm is the most important access site complication following cardiac catheterization. Ultrasound-guided compression repair is a safe and effective therapeutic modality with variable failure rates and risk factors. The aim of this study was to investigate which factors were associated with a higher incidence of ultrasound-guided compression repair failure for post-cardiac catheterization femoral pseudoaneurysm. Methods: Data were retrospectively collected from medical records at King Abdullah University Hospital during the period from January 2011 to December 2016. A total of 42 patients with post-cardiac catheterization femoral pseudoaneurysm had attempted ultrasound-guided compression repair. Data regarding patients, procedure and aneurysm-related factors were evaluated by univariate analysis and multivariate logistic regression. Results: Ultrasound-guided compression repair failed in 31% of the patients. Patients with body mass index of ⩾28 kg/m 2 , platelet count of ⩽180,000/L, time lag (age of aneurysm) of >48 h following puncture time, aneurysmal neck diameter of ⩾4 mm and communicating tract length of  48 h (odds ratio = 5.7), body mass index ⩾ 28 kg/m 2 (odds ratio = 7.8), neck diameter > 4 mm (odds ratio = 14.4) and tract length 48 h, body mass index ⩾ 28 kg/m 2 , wide neck diameter > 4 mm and short aneurysmal communication tract < 8 mm
